I can't think of any reasons to not return my Droid before my 30 days are up in order to pick up a DroidX when it comes out in July.
I over research everything, and want to make sure I'd like the DroidX over the Droid.
The DroidX doesn't have any moving parts to trap dust, grit, or grime. It should be much easier to keep clean for those who work with their hands. I picked up the Droid last Saturday the 5th and since I'm an industrial electician, have been keeping it in a zip lock baggy while in my pocket at work.
I wonder how difficult it will be to get rid of the MotoBlur UI, because I REALLY like the plain Android OS UI.
I have to be very careful with use at work, because the battery drains down rather quick. I disable GPS, turn the backlight down to minimum, disable Gmail synch (since I don't use Gmail), and have my rocketmail.com (Yahoo.com) email account set to check every hour. If I were to keep the Droid, I would be forced to get the Seidio 2800 mAh battery, which only gives me one case to choose from. I mean, what's the point of having a smartphone if you can't actually use the "smart" part of it?
As long as the call quality on the DroidX is as good as it is on the Droid and the battery life isn't any worse than it is on the Doid, then I would imagine it would be a go.
